A convenient one-pot synthesis of thiopyrano[4,3-b]pyran derivatives under LiOH·H2O/EtOH/ultrasonic conditions

Various derivatives of thiopyrano[4,3-b]pyran structure are synthesized via a multicomponent procedure starting from tetrahydro-4H-thiopyran-4-one, aromatic aldehydes, and malononitrile. Reactions take place by the use of catalytic quantities of LiOH·Hsu

Green chemistry preparation of MgO nanopowders: efficient catalyst for the synthesis of thiochromeno[4,3-b]pyran and thiopyrano[4,3-b]pyran derivatives

A mild and efficient method for the synthesis of thiochro meno[4,3-b]pyran and thiopyrano[4,3-b]pyran derivatives using MgO nanopowders as a catalyst is described. The MgO nanopowders were prepared via a green biosynthesis method using an extract of Rosma
